design efforts, stakeholder engagement and mixes of various policy instruments. For policy makers, I am confident that these detailed case studies will prove a treasure trove of practical tools and insights. Urban Efficiency II is based on research conducted by TMG. In publishing our results, we would like to thank the efforts of CSR Design Green Investment Advisory (especially Tomoko Takagi) for much dedicated work. We also express much appreciation to Greg Trencher from Clark University as the lead author of the report, and for providing important insights from the perspective of the cases studies as a whole. This has deepened our understanding of city efforts in the area of building energy efficiency. Finally, we extend special thanks to the contributors from each surveyed city sparing the time out of busy schedules to cooperate for interviews, provide additional information and correct the drafts. It is my sincere hope that this report too will be an important reference not only for other C40 and PBE network members, but also for colleagues in other cities around the world.

Frankie Downy C40 Cities Climate Leadership Group, London At the C40 Summit in Mexico City, C40’s Deadline 2020 research revealed the scale of action needed to ensure our cities follow a pathway consistent with the Paris Agreement, and limit global temperature increase to 1.5 degrees. If this is to happen, the next four years are critical and require a huge increase in the rate of climate action in cities. The member cities of the C40 represent 11% of the global population and a quarter of global GDP. They are the biggest cities in the world, and have a big responsibility to reduce emissions. But they are also the leading cities, innovative and ambitious in their plans and actions to tackle climate change. Deadline 2020 highlights that it is the Buildings Sector where the highest proportion of actions must be taken. And within the Buildings Sector, retrofit and financial support or incentives for commercial and residential buildings together are projected to deliver 70% of emission savings. The C40 Private Building Efficiency (PBE) Network, co-led by Tokyo and Sydney, supports cities to replicate, improve and accelerate climate action across the commercial and residential sectors. This report, the second in a series, was produced using examples from the PBE Network. Like the first report, it serves as a reference and evidence base for city officials when developing or improving building energy policies. The first report was incredibly useful for cities who used it to incorporate best practices from around the world, including financial incentives, sectoral benchmarking, and building optimisation programmes into their energy plans and roadmaps. Other cities used it as an evidence base to push for the introduction of new, ambitious building energy policies or expand already successful schemes. We hope this report will prove just as valuable. To limit warming to 1.5 degrees all cities, not just C40 cities, are going to need to take action. Therefore C40 and Tokyo Metropolitan Government (TMG) are pleased to be able to share the valuable lessons and analysis in this report with policy makers around the world. C40 would like to thank all those involved in producing the report - the generosity of TMG and in particular the dedication of Yuko Nishida; Greg Trencher from Clark University for his lead role in writing the report; and the efforts of CSR Design Green Investment Advisory, in particular Tomoko Takagi. And finally, to the city staff who contributed their time to help create this valuable resource.
